“…13). The molecular parameters of acyclic isoprenoids, terpanes and steranes for oils D15O and DN8O are similar to oils which were generated from the source rocks within the Middle Permian Pingdiquan Formation (P 2p ) and its age equivalent Lower Wuerho Formation (P 2w ), as documented in the previous studies (e.g., Zhou et al, 1989;Clayton et al, 1997;Pan and Yang, 2000;Chen et al, 2003a;Pan et al, 2003;Cao et al, 2005Cao et al, , 2006Cao et al, , 2012. Chen et al (2003a) and Pan et al (2003) documented molecular characteristics of oil DN1O from the interval 2760-2767 m of the Jurassic sandstone reservoir and oil components from oil-containing sandstone DN1-1 at 2764 m, respectively from borehole DN1 located near borehole DN8 (Fig.…”

“…Numerous studies have demonstrated that the most important source rocks in the basin are within the Permian strata and for most reservoirs, especially in the northwestern area, oils are dominantly derived from three Permian source rocks, which from old to young are: (1) the Lower Permian Jiamuhe Formation, (2) the Lower Permian Fencheng Formation, and (3) the Middle Permian Lower Wuerhe Formation in the northwestern area and its ageequivalent analogs Pingdiquan Formation in the eastern area and the Lucaogou Formation in the southern basin margin (Jiang and Fowler, 1986;Jiang et al, 1988aJiang et al, ,b, 1990Zhou et al, 1989;Graham et al, 1990;Carrol et al, 1992;Zhang et al, 1993;King et al, 1994;Clayton et al, 1997;Carroll, 1998;Wang andKang, 1999, 2001;Pan and Yang, 2000;Pan et al, 2003;Cao et al, 2005Cao et al, , 2006.…”

“…The maturity of these source rocks is middle to high at present [30] . According to Cao et al [31] , seven sets of reservoir-caprock combinations can be identified, and commercial oil and gas pools have been discovered in all of these combinations from Carboniferous to Cretaceous [32] (Figure 1(b)). The widely developed fault-controlled systems are main pathways for petroleum migration [32] .…”

Electronic probe microanalysis (EPMA) results of reservoir calcite cement from fourteen core samples in the Junggar Basin show that Mn-content varies largely between different samples from below the detect limitation to 4.14%, while it displays a generally good correlation with oil-gas shows. This, therefore, likely indicates that concentration of the Mn-content of the calcite cement has a close relation to the intensity of petroleum fluid charging during hydrocarbon secondary migration. In order to assess this hypothesis, oxygen and strontium isotopic measurements on sixteen calcite veins host in source sequences were carried out to investigate the feature of the oil-source petroleum fluid. Analytical results imply that during hydrocarbon generation and migration, deep hot fluid has dissolved volcanic minerals interlined between mudstone source rocks. As Mn is a kind of typical trace element enriched in volcanic rocks, it is reasonable to conclude that the petroleum fluid formed in the source sequences would be Mn-rich. Consequently, calcite cements precipitated from such Mn-rich petroleum fluid would be Mn-rich accordingly. Due to the geologic chromatographic effect during migration along reservoir rocks, the decreasing of the Mn-content of the reservoir calcite cements indicates the migration direction. Then, this novel geotracer was further successfully applied in the study of hydrocarbon migration in the Junggar Basin in combination with organic geochemical analyses during the hydrocarbon migration. The Mn content of the reservoir calcite cement appears promising as a novel inorganic geotracer for the petroleum migration. This paper represents a search for novel indicators of secondary petroleum migration in tectonically complex basins based on fundamentals of the reservoir fluid-rock interactions.Petroleum migration, inorganic geochemistry, water-rock interaction, reservoir calcite cement, the Junggar Basin Petroleum migration bridges hydrocarbon generation and accumulation, and hence the ability to trace migration of oils from source rock to reservoir not only involves geochemical fundamentals of petroleum fluid activity during the migration, but also could assist in the identification of new, viable hydrocarbon kitchens and accumulations of petroleum [1][2][3] . Thus, it is of great significance, either fundamentally or economically, to search geoindicators of the hydrocarbon migration. For decades, as it is universally acknowledged that petroleum is generated through the thermal alteration (maturation) of buried organic matter, researchers often apply organic geochemical methods in the study of migration geotracers [4] , such as oil-oil and oil-source correlation

Lateral Migration of Petroleum in the Jurassic Toutunhe Formation in the Fudong Slope, Junggar Basin, China

et al. 2014

New oil reservoirs have been discovered recently in the Jurassic Toutunhe Formation in the Fudong slope, Junggar basin in China. The process and mechanism of lateral petroleum migration in the Jurassic System in the Fudong slope was investigated based on the geological analysis of the strata, porosity and permeability of the reservoir rocks and geochemistry on oil-source correlation and oil-oil correlation. The results indicate that hydrocarbons of the Toutunhe Formation were primarily derived from the Middle-Lower Jurassic and Middle Permian source rocks of the western Fukang Depression and migrated along the axis from west to east. The thickness, sand/strata ratio, porosity and permeability of the Toutunhe 2 member are all better than that of the Toutunhe 1 member, making it the main carrier bed of the hydrocarbons lateral migration.
